Boeing and FAA manipulated 737 Max tests
The report released on Friday by the Senate Commerce Committee raised questions about testing in 2020 of a key safety system known as MCAS tied to both fatal crashes, which prompted the planes to nosedive shortly after take-off.
It also said that the US aviation regulator, the Federal Aviation Administration (FAA) and Boeing officials “had established a pre-determined outcome to reaffirm a long-held human factor assumption related to pilot reaction time.”
“It appears, in this instance, the FAA and Boeing were attempting to cover up important information that may have contributed to the 737 Max tragedies,” the committee said.
The regulator added that the committee's report contained "a number of unsubstantiated allegations.” and that its review of the 737 Max had been thorough. It said it was confident that safety issues with the aircraft had been addressed.
The Senate Commerce Committee report cited a whistle-blower who claimed that Boeing officials prompted test pilots to use a particular control before an exercise. ■
